documentation

The BornProfiler documentation currently consists mostly of the doc strings or placeholders.

• Examples and use of the scripts: how should the typical user make use of the package?
  • describe workflow and individual steps
  • add figures that show typical output
• More prose is needed to explain use of the classes for developers.
• No "next" and "previous" links that allow one to quickly click through.
• Customize the theme.
